Any diuretic, be it synthetic or natural, increases the level of urine your body would typically eliminate. Normally, the kidneys create urine by filtering out potassium, sodium ions, and of course water from the bloodstream. Via a complicated system, the kidneys give back a precise level of those ions and some of the water as well back to the blood so the levels in the bloodstream stay constant and consistent. All of the other extra water ends up in the bladder in the form of urine. When illness makes the blood flow to the kidneys much less, they react to this by storing extra water, this is the basic and principle reason diuretics are given to prospective patients. You also might be aware that medical practitioners also recommend various diuretic treatments to help with high blood pressure, certain liver diseases, and congestive heart failure; all of these illnesses cause some type of water retention.
Often people who are trying to reduce or lose excess weight look into a diuretic cleanse or other natural diuretics like a diuretic juice. If this is something you are trying to do, you should be made aware that any loss of weight you lose as a result of any diuretic use natural or not will just be short lived. Excessive use or an overuse of any diuretics including natural options like diuretic juices without any sort of proper doctor supervision can bring on dehydration; this can lead to kidney harm any out of whack levels of electrolytes like the potassium and sodium electrolytes mentioned earlier, which is crucial for heart function, liver and kidney health and function too. When electrolytes are in an imbalanced state, the body is at a very severe risk for some kind of heart failure and even sudden death. Having said that cautionary message, I advise avoiding foods with high levels of sodium which include sports drinks, and other more processed foods and beverages; this is one of the reasons why many fruit and veggie juices act as diuretic juices, because of their naturally low levels of sodium.
There are beverages that I can recommend specifically for natural diuretic use. Any drink that has alcohol and caffeine have a diuretic result, and several other juices including celery juice, onion juice, watermelon juice, and asparagus juice are known to have diuretic effects on the body. A cranberry juice diuretic or lemon juice diuretic drinks are also effective as well. There are diuretic herbs as well that can be used alongside the juices or by themselves. Some of these are corn silk, parsley, and hawthorn which are staples of alternative remedies. Of the ones mentioned, the hawthorn herb is the most potent. I would advise though that IF you are prescribed any kind of diuretic by your doctor that you consider his advice first before trying to treat yourself.
